Hi Richie just like to ask you, how long have you used this make of battery? The only reason I ask is. That a number of members have said to use Calcium battery ONLY, Yet I have checked this battery and it dose not state that it is a Calcium battery, but dose say that it gives out 30% more power when needed. The only thing I concerned about is the life of the battery, if it is not a Calcium battery? thanks (pain in the ---) haha Paul.
